HP ScanJet Enterprise Flow 5000 s4, 7000 s3 - Scanner operation problems

The following topics describe how to troubleshoot problems with the scanner operation.

Connection issues

Check the USB connection

Check the physical connection to the scanner.
  • Use the cable that was included with the scanner. Another USB cable might not be compatible with the scanner.
  • Ensure that the USB cable is securely connected between the scanner and the computer. The trident icon on the USB cable faces down when the cable is properly connected to the scanner.
If the problem persists after verifying the above items, try the following:
  1. Do one of the following tasks depending on how the scanner is connected to the computer:
    • If the USB cable is connected to a USB hub or a docking station for a laptop, disconnect the USB cable from the USB hub or the docking station, and then connect the USB cable to a USB port on the back of the computer.
    • If the USB cable is directly connected to the computer, plug it into a different USB port on the back of the computer.
    • Remove all other USB devices from the computer except for the keyboard and the mouse.
  2. Press the Power button to turn off the scanner, wait 30 seconds, and then turn on the scanner.
  3. Restart the computer.
  4. After the computer has restarted, try using the scanner.
    • If the scanner works, reconnect any additional USB devices one at a time; try the scanner after connecting each additional device. Disconnect any USB devices that prevent the scanner from working.
    • If the scanner does not work, uninstall and then reinstall the HP ScanJet drivers and software.

Buttons are not working properly

If the buttons are not working properly, complete the following steps.
  1. A cable might be loose. Ensure that the USB cable and the power supply are securely connected.
  2. Turn off the scanner, wait 30 seconds, and then turn the scanner back on.
  3. Restart the computer.
  4. If the problem still persists, there might be a problem with the control panel. Contact HP Support at www.hp.com/go/sj5000s4 or www.hp.com/go/sj7000s3.

LCD issues

The LCD is having display issues

The following symptoms indicate a problem with the scanner control panel.
  • LCD issues: The display is blank, or part of the display content is missing.
  • LED issues: LEDs are not working, or are staying in the wrong state.
If the scanner exhibits any of these problems, contact HP support at www.hp.com/support.

The scanner buttons are not working as expected

The following symptoms indicate a problem with the scanner control panel.
  • Button issues: Buttons are unresponsive, or the wrong action occurs when you press a button. For example, you get a single-sided scan when you press the Duplex Scan button.
  • LED issues: LEDs are not working, or are staying in the wrong state.
If the scanner exhibits any of these problems, contact HP support at www.hp.com/support.

Scanning performance issues

Scanner does not scan immediately

Make sure that the document feeder hatch is closed, and that the scanner is turned on.

Scanner is scanning items very slowly

When scanning to edit text, the optical character recognition (OCR) causes the scanner to scan more slowly, which is normal. Wait for the item to scan.
note:
For the best OCR results, scanner compression should be set to the minimum compression level or be disabled.
Scanning at a higher resolution than necessary increases scanning time and creates a larger file with no additional benefit. If you are scanning at a high resolution, set the resolution to a lower level to increase scanning speed.

Scanner scans only one side of a two-sided page

Verify that the selected scan shortcut specifies two-sided scanning.

Scanned pages are missing at the scan destination

When scanning, pages that stick together are scanned as one item. Check to confirm that scanned pages are not stuck together.

Scanned pages are out of order at the scan destination

  • Verify that the page order of the original document is correct before placing the document face down into the input tray.
  • Make sure that there are no staples, paper clips, or any other attached material (such as adhesive notes) that might cause the pages to feed incorrectly.
  • Verify that pages are not stuck together.

Scan files are too large

  • Most scanning software allows a smaller file size to be selected when selecting the output file type. For more information, see the Help for the scanning software being used.
  • Verify the scan resolution setting (for more information, see the Help for the scanning software being used):
    • 200 dpi is sufficient for storing documents as images.
    • For most fonts, 300 dpi is sufficient for using optical character recognition (OCR) to create editable text.
    • For Asian fonts and small fonts, choosing a higher resolution is recommended.
    note:
    For some special black dot background scans, saving the image as a .tif file might make the image smaller.
    Scanning at a higher resolution than necessary creates a larger file with no additional benefit.
  • Color scans create larger files than do black and white scans.
  • If scanning a large number of pages at one time, consider scanning fewer pages at a time to create more, smaller files.

Issues with text recognition (OCR)

The scanner uses optical character recognition (OCR) to convert text on a page to text that can be edited on a computer.
  • If text can be scanned but cannot be edited, make the following selections before scanning:
    • Select a scan shortcut that supports OCR. The following scan shortcuts support OCR:
      • Save as PDF
      • Email as PDF
      • Save as Editable Text (OCR)
      • Send to Cloud
    • Select one of the following OCR-based, output-file types from the File Type drop-down box:
      • Text (*.txt)
      • Rich Text (*.rtf)
      • Searchable PDF (*pdf)
note:
If an OCR-based, output-file type is not selected, the document is scanned as a graphic and the text is not editable.
  • Check the originals
    • The software might not recognize text that is tightly spaced. For example, if the text that the software converts has missing or combined characters, "rn" might appear as "m".
    • The accuracy of the software depends on the image quality, text size, and structure of the original and the quality of the scan itself. Make sure that the original has good image quality.
    • Colored backgrounds can cause images in the foreground to blend too much.
  • If the scanner strips are dirty, the scan file does not have optimum clarity. Make sure that the scanner strips are clean.
